Thermostat housing Plug

Does anyone know what kind of tool I need to remove the plug on the side of the thermostat housing to install a by-pass coolant system? It's square shape and it's not a 3/8" socket or 1/4". BTW it's a 2002 PSD

I had same problem. Take a cheap short 3/8 extension and grind it square so it will fit. Worked great for me. Quick and easy!

My tools ain't cheap. Save the extension.

Grind a common bolt to use as a tool. It's about 5/16" on a side.

I went to several auto parts/ tool places today and nobody has a 5/16" square 'tool' to remove the plug. Why did they use a plug you couldn't find a common tool to remove it with?

You might be able to stick a large screwdriver in there and use a crescent wrench or vice grips on the screwdriver.

Go and buy a set of square E-Z outs. You will more than likely find one that fits. If not then you can grind off the end till it does fit.
